DETAILED DESCRIPTION

Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment, but mean “one or more but not all embodiments” unless expressly specified otherwise. The terms “including,” “comprising,” “having,” and variations thereof mean “including but not limited to” unless expressly specified otherwise. An enumerated listing of items does not imply that any or all of the items are mutually exclusive and/or mutually inclusive, unless expressly specified otherwise. The terms “a,” “an,” and “the” also refer to “one or more” unless expressly specified otherwise.

In the above description, certain terms may be used such as “up,” “down,” “upper,” “lower,” “horizontal,” “vertical,” “left,” “right,” and the like. These terms are used, where applicable, to provide some clarity of description when dealing with relative relationships. But these terms are not intended to imply absolute relationships, positions, and/or orientations. For example, with respect to an object, an “upper” surface can become a “lower” surface simply by turning the object over. Nevertheless, it is still the same object. Further, the terms “including,” “comprising,” “having,” and variations thereof mean “including but not limited to” unless expressly specified otherwise.

Additionally, instances in this specification where one element is “coupled” to another element can include direct and indirect coupling. Direct coupling can be defined as one element coupled to and in some contact with another element. Indirect coupling can be defined as coupling between two elements not in direct contact with each other but having one or more additional elements between the coupled elements. Further, as used herein, securing one element to another element can include direct securing and indirect securing. Additionally, as used herein, “adjacent” does not necessarily denote contact. For example, one element can be adjacent another element without being in contact with that element.

As used herein, the phrase “at least one of” or “one or more”, when used with a list of items, means different combinations of one or more of the listed items may be used and only one of the items in the list may be needed. The item may be a particular object, thing, or category. In other words, “at least one of” means any combination of items or number of items may be used from the list, but not all of the items in the list may be required. For example, “at least one of item A, item B, and item C” may mean item A; item A and item B; item B; item A, item B, and item C; or item B and item C. In some cases, “at least one of item A, item B, and item C” may mean, for example, without limitation, two of item A, one of item B, and ten of item C; four of item B and seven of item C; or some other suitable combination.

Furthermore, the described features, structures, or characteristics of the invention may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided, such as examples of programming, software modules, user selections, network transactions, database queries, database structures, hardware modules, hardware circuits, hardware chips, etc., to provide a thorough understanding of embodiments of the invention.

The illustrated embodiment also includes a bearing 504. In some embodiments, the bearing 504 is positioned within the pivot joint 408 to support the drive shaft 502 within the pivot joint 408. The bearing 504 may be a needle bearing, a journal bearing, a ball bearing, or the like. In the illustrated embodiment, the bearing 504 extends along a portion of the pivot joint 408. In other embodiments, the bearing 504 extends along more or less of the pivot joint 408.

In the illustrated embodiment, the drive shaft 502 also includes a stop 506. In some embodiments, the stop 506 forms a physical structure positioned to interact with the pivot joint 408 to limit the rotation of the drive shaft 502 relative to the pivot joint 408. In some embodiments, the stop 506 is a post that extends from the drive shaft 502 and aligns with a stop track 508. In some embodiments, the stop track 508 is a slot or hollow formed in a portion of the pivot joint 408. The stop track 508 may have a length corresponding to a movement pattern of the pivoting door plate 208 relative to the base plate 202. For example, the length of the stop track 508 may correspond to a degree of rotation of the pivoting door plate 208. In some embodiments, the degree of rotation of the pivoting door plate 208 is approximately ninety degrees.

In some embodiments, the motor 206 is configured to detect one or more inputs. For example, the motor 206 may detect that the stop 506 has reached an end of the stop track 508, when an obstruction is in the path of the pivoting door plate 208, when a start or stop condition occurs, and the like. One or more of the sensor 204 or the motor 206 may be configured to display a status of the access 130 on a light, sign, or other display apparatus.

FIG. 9 is a partial cross-sectional view illustrating one embodiment of the conduit access 130 with a cross-section of the pivot joint 408. In the illustrated embodiment, the pivoting door plate 208 is in the close position relative to the base plate 202. As shown, the pivoting door plate 208 may be coupled to the pivot joint 408 to allow the motor 206 to apply a force to the pivoting door plate to open or close the pivoting door plate 208 or maintain the pivoting door plate 208 in an open or closed position.

FIG. 10 is a flow diagram illustrating one embodiment of a method 1000. The method 1000 includes, at block 1002, pivoting a pivoting door plate about a pivot joint of a base plate to move the pivoting door plate parallel to, and across a front side of, the base plate to expose a pass-through disposed in a center of the base plate.

At block 1004, the method 1000 includes receiving an object at the pass-through of the base plate. At block 1006, the method 1000 includes pivoting the pivoting door plate about the pivot joint to close the pass-through of the base plate to align a stop notch of the pivoting door plate with a stop feature of the base plate.
